SPECIFICATION formingpart of Letters Patent No. 700,468, dated May.2 O, '1902.-

1 A lication fina'nmmtercaisim. seminasmz ts. tNoinodel.)

To all-whom (it may concern 1 Be it known that I,WILLIAM P. APPLE YARD, a citizenof the United States, and a resident of New Haven, in the county of New Haven and State ofConnecticutphave made and in; vented certain newand useful Improvem outs in Machines for Covering Strips of Timber With Metal, of which the following is a specification. j m Myinvcntionrelates to an improvement in machines for covering strips of wood With metahand more particularly upon the machine asshown and described in LettersPatentfgranted to 'me May 23, 1899, and burnl5 bered'625,531. T By reference to the said patentit will be seen that the machine as heretofore constructed consists of a feed-roll, a superposed primary roll adapted to turn the edges of the metal downwardly as the strips of metal and wood pass below the same, and

two horizontal rolls for properly shaping the edges of themetal andsimultan'eously bending or turningiit around the tongue and into the groove formed on the opposite edges of the wooden'strip, a finishingroll'being e n'-' ployed in conjunction with thehorizontal tions to gradually co mple to the shaping, bending, and looking of the edgesof said metal strip, these successive steps bein g effected by several pairs of rollers and stationary devices,

in that in the finished product the metal fits tighter and closer to the wooden strip and is more firmly. and securelylocked thereto. To

carry out this method, I have devised a machine consisting of certain novel features of constructiouand combinations of parts, as

will be hereinafter fully described, and pointed out in-the claims.

Fig. 2 is a viewin side elevation. Fig. 3is'a longitudinal sectional view taken on the line 3 3 showing the horizontal adjustment of the bearim'g-boxes. Fig. '5 is a bottom plan view Fig."6 is asectional located between the rollers. Fig. 8'is a bottom plan'view of the -forwardfguide shoe.

Figs. 9, 10, ll, 12, 13,14, and 15 are sectional views showing the successive step s of bending and locking the sheet metal to the'wooden 165 strip, Fig. 9 being taken on the. li-ne'9 9 of 1 Fig. 1, Fig. 11 being taken on the line 11 11 of Fig. 1, Fig. 13 on the 1inel3 13 of Fig. 1, and Fig. 15 on theline 15 15 of Fig. 1. Fig. 16 is'a sectional view of one ofthe adjusting devices for the horizontal rolls. I

Referring to the drawings, 2 represents a stand or support, preferably formed of metal and of any desired shape, to which is bolted or otherwise secured the fram'e,-preferably made in box-like form that is, with-front and rear plates 3 4, side plates 5 6, and with the top plate 7, th'e'latter being curved down- I wardlyfat about the center of its length to form the two transverse receptacles 8 9, sepa-' rated by the transverse webor'flange 10. To the forward end of the plate'7 are boltedthe guide-plates 11, preferably of the form as illustrated in Figs. 1 and 9, elongated slots 12 be-v ing formed in the said plate 7 through which @the fastening bolts 13 pass, whereby said guide-plates -11 may .behorizontally adj usted toward or away from each otherto accommodate strips of timber of difierent widths.

These guide-platesjareconstructed with the vertical flanges 14: and shoulders or ledges 15,

whereby in :practice'the strip oftimber 16 under operation will rest upon the base-plate 7 and between the adjacent edges '17 ofthe guides, the strip of copper or sheet metal 18 5 Fig. 4 is a'detailsectional view 55 ward the firstpair of rollers or formers, I secure to the guides 11 the plates 19, the lower surfaces of which bear on the upper surface of the metal strip, said plates 19 being re-- tained in place by means of the bolts orsorews ing mounted on the shaft 23 and the roll 22 on the shaft 24,these rollers, as hereinafter described, being employed for bending the edges of the metal 18 into approximately the shape of the edges of the strip of timber 16, as clearlyillustrated in Fig. 10. The lower roller or sheath-former 22, locatedin the receptacle?) of the frame, is preferably made of three parts-namely, the two dies 25 26 and the intermediate roller 27--said dies being bolted or otherwise secured to said r0ller27, as illustrated in Fig. 6, and mounted on the shaft 24, the latter being supported in suitable bearings formed in the sides 5 6 of the frame. The upper sheath-former 21 is shown as made in one piece, its shaft 23 being-sup. ported in bearings adjustably secured in the sides 5 6 of the frame, which sides .are extended upwardly, as illustrated at 28. These extensions of the sides of the frame are cut out, as illustrated at 29, to receive the bearings for the shaft 23, which bearings, as illustrated in Fig. 4, are preferably made in three pieces or sectionsnamely, the upper. section 30, middle section 31, and lower section 32, the said upper and lower sections being dovetailed into the middle section in order that they may be simultaneously raised or lowered with each otherand with the contained shaft Into the upper sections 30 of the bearings are secured the lower ends of the'rods 33, the upper portions of which are threaded in openings formed in the-yokes 34, the latter being bolted or otherwise secured to the upper edges of the extended sides 28 of the frame,- the extreme upperends of said rods.

having secured thereto or formed thereon the handles 35, whereby said rods may be raised or lowered and the bearings for the upper-roller 21 correspondingly vertically adjusted, this construction and arrangement of parts allowingthe upper roller 21 to be adjusted toward or away from the lower roller 22 in accordance withthe thickness of timber and metal, and also permitting both rollers to be removed or detached from their respective shafts and others substituted.

As illustrated in Figs. 6 and 10, the upper roller or former 21 is provided on its surface and near one edge thereof with the bead 36 and near its opposite edge with the groove 37, the lower roller or former having its die 25 provided with the flange 38 and its die 26 with the groove 39, these several parts so operating with relation to each other that the strip of metal 18 has its edges bent to approximately conform to the shape of the tongue 40 which I term the sheath-formers, the roller 21 be and groove 41, formed on and in the edges of the strip of timber 16, the centraltportion of the metal strip being retained in its flattened condition and against the timber by reason =The' under side of the plate 43 is provided at one side thereof with the downwardly-projecting strip 46, extending from about the center of the length of said plate to the rear end thereof, the underside orsurface of said. strip 46 being inclinedthat is, starting at about the center of the length of said plate 43 the same increases in thickness toward its rear end, the purpose and effect .of this projection being to grad nally bend downwardly that.

edge of the metal shaped to fitaronnd thetongue 40 of the timber as the latter and the metal strip pass under the shoeandbetween the flanges thereof, as illustrated in Fig. 11. Behind thisguide-shoe 42 is located a second pair of rollers, consisting of the upper roller.

47 and the lower roller 48, the latter being contained within the receptacle 9, formed in the top of the frame and mounted upon the shaft 50, the ends of which shaft are supported in suitable bearings provided in the sides of the frame,and the formeror top roll 47, which I term the rear sheath-former, being mounted upon the shaft 51, this shaft being supported in bearings located in the side extensions 28. These bearings are in all respects similarly constructed and arranged as the bearings supporting the shafts of the forward rollers illustrated in Fig.4, and, as in the former instance,are raised and lowered by meansof verticalrods 52, threaded in the.

yoke-piece 34 and provided on their upper ends with the handles 53.

The lower roller 48, whichI term the rear sheath-carrier, has its surface provided with teeth or corrugations similar to the central.

portion 27 of the roller 22 for the purpose of biting into the underside of the strip of timber and feeding the same through the lllilr.

chine, the upper roller or rear sheath-former 47 having the shape or contour as shown in sec-' tion in Fig. 12that is, with the downwardlyprojecting flanges 54 55-the object of which is to continue the downward bending of that edge of the metal shaped to fit around the tongue 40 of the timber, and also to bend.

downwardly at approximately right angles the opposite edge of the metal shaped to fit into the groove 41.

Back of the rollers 47 48 is located the rear guide-shoe 56, a bottom plan View of which is shown in Fig. 5. This shoe consists of the 7 plate 57, provided with thelateral arms 5.8; through whichthe shoe is boltedor otherwise secured to the plate 7 of the frame. -'lhe shoe vIO is providedon its under-surface with the guides59, between which the stripoftimber and its partially-shaped metal stri pass-,and also 'W'ith'the shoulders 6061, which latter bears upon that-edge of the metal shaped totit around thetongue and forces it into proper place upon the upper surface of said tongue, and the former uponthe opposite-shaped metal edge to partially bend it into place, as

- clearly illustrated in" section inFig. 13:

In the openings. or recesses 62, formed in the upwardly-extended sides 28 of theframe, are located the adjusting-caps 63, (shown in section in Fig. 16,) adapted to' be vertically raised and lowered by means of therods 64, the'lower ends of which latterare secured to said'ca-ps and the upper portions of which are threaded into the brackets 65, the ex treme upper ends of said rods-beingprovided with handles 66 tofacilitate turning the same;

To the bearing-caps 63 are secured the hearingplates 67, adjustable horizontally andv carrying at their inner'free ends the horizon tal rollers 68 69, the former being provided with agroove 70, adaptedto lock the metal tightly around the tongue 4.0 of the. wooden strip, andthe latter'-that is, the roller 69 being provided with the ilangeor bead 71 to carry the opposite edgeofi the metal strip into the'groove 41 of said wooden strip, as illustrated'in section in Fig. 14. By'me'ans of.

this construction and arrangement of parts it will be'understood"that-the edges of the metal strip are first shaped to approximate .thatof the edges of the timber and are then gradually. bent downwardly into theirproper position, the horizonta'l rollers locking them in place. As there is some tendency, however, of the metal to leave thewood as the covered strip issues from between the hori-.

zontal rolls 68 69, I have secured immediately behind the latter the guide-formers 72 73,

- their inner ends being "shaped as shown in section in Fig. 15-that is, shaped to receive the tongue-and-groovededges of the metalcovered strip, the efiect being to assist in looking the metal in place and prevent the separation of the wooden and metal strips as the finished material issues fromthe machine.

While I have shown and described my improved machine as provided with rolls or formers adapted to 'cover a strip of timber provided on its edges with'a tongue and groove, I do not intendto limit myinvention thereto,

as by meansof rollers of difierent sizes andshapes, which may be readily substituted for those hereinbefore referred to,-I"am 'enabled to cover wooden strips having different shapes or outlines, the machine being so constructed that the rollersand' formers may be readily removed and others substituted therefor.

In order to impart the 'necessary rotation to the several rollers, I secure to the stand or support'a bracket 74, in which is journaled oneiendof the shaft 75, the opposite endbe-U' l l I 'ingsu'pported in the-bearings forme'dinthri side 5. ofthe frame. Uponuthis" shaft ar'e mounted the tight and loose pulleys 76 7 7 ,;.by 1 means of -which ,mjotiom is imparted to said-1 shaftmntl.tothegear, 78 the latter meshitig I with the gear 79, secured tooneendoii-the shaft 50.
